<p>
      The <a class="link" href="libgda-5.0-Configuration.html" title="Configuration">Configuration section</a> details how to manage data sources
      definitions. To define a data source, one needs to create and fill a 
      <a class="link" href="libgda-5.0-Configuration.html#GdaDsnInfo" title="struct GdaDsnInfo">GdaDsnInfo</a> structure, and use the
      <a class="link" href="libgda-5.0-Configuration.html#gda-config-define-dsn" title="gda_config_define_dsn ()">gda_config_define_dsn()</a> function.
    </p>
<p>
      For example the following code defines a data source:
      </p>
<pre class="programlisting">
GError *error = NULL;
GdaDsnInfo dsn_info = {
    "My DSN",
    "MySQL",
    "Sample MySQL data source",
    "HOST=myserver;DB_NAME=testdb"
    NULL,
    FALSE
};
if (!gda_config_define_dsn (&amp;dsn_info, &amp;error)) {
    /* an error occurred, the details are in error */
    g_error_free (error);
}
      </pre>
